Catalogs of Solar Proton Events as a Tool for Studying Space Weather
Vlasova, N. A.; Bazilevskaya, G. A.; Ginzburg, E. A. +8 more
Distinguishing features of a series of solar proton event (SPE) catalogs for the 20th-24th cycles of solar activity are described. The results of a comparative analysis of the 23rd and 24th cycles of solar activity performed according to the data of a series of SPE catalogs are presented. The opportunities provided by SPE catalogs for studying spa…
Physical Calibrations of the FREND Instrument Installed Onboard TGO Martian Orbiter
Mitrofanov, I. G.; Golovin, D. V.; Litvak, M. L. +10 more
The article presents results of ground calibrations of the FREND neutron telescope installed onboard the TGO spacecraft of the Russian-European ExoMars project. The main goal of the FREND space experiment is to measure hydrogen content in the subsurface layer of Mars to a depth of 1 m. High resolution maps of water mass fraction in the regolith ar…
A Comparative Analysis of Quasi-Periodic Processes in the Magnetospheric Current Sheet and the Current Sheets of the Solar Corona
Zimovets, I. V.; Lukin, A. S.; Artemiev, A. V.
Reconnection of magnetic field lines represents a universal process of releasing the stored energy of the magnetic field and its transformation into the thermal energy of plasma and the energy of accelerated charged particles. The initialization and proceeding of the magnetic reconnection process are essentially related with the dynamics of a spat…
